Portability:

Notebooks come in all shapes and sizes. Some are thinner and lighter but may not have the same hardware capabilities as their thicker, heavier counterparts. If you plan to use your notebook for travel, you'll likely want something that's easy to haul through the airport and onto the plane. If you plan to use your notebook around the office, in the meeting room, and at home, you may trade ultra-portability for extra features. Generally, most notebooks intended for business use will be of a respectable weight and size, making at least this portion of the decision-making process a little easier.
